He created Coulomb’s law. It is law of physics describing the electrostatic interaction between electrically charged particles.
"... the moment of the torque is, for wires of the same metal, proportional to the torsional angle, the fourth power of the diameter and the inverse of the length of the wire..."
Personal Life- Father was an inspector of the Royal Fields in Montpellier. Mother came from wealthy family. Moved to Paris and Coulomb went to Collège des Quatre -Nations . Went into the military and became a Captain. Later returned to his studies.
Education- Went to Collège des Quatre -Nations . Studied Mathematics.
Positions- He became Captain in the military. He became one of the first members of the French National Institute and was appointed inspector of public instruction in 1802.
Contributions- He discovered an inverse relationship of the force between electric charges and the square of its distance, later named after him as Coulomb’s Law.
